OBD II is an automotive diagnostic and monitoring application that supports English and German. It communicates with the vehicle's in-vehicle terminal via Bluetooth through a mobile phone to perform fault diagnosis and driver assistance functions. It features fault code reading and clearing, dashboard monitoring, performance testing, trip analysis, and other automotive diagnostic and analysis functions. It also supports high-speed data transmission and boasts low power consumption and ultra-low energy efficiency.

Warning:
1. Supports adapters that operate via Bluetooth.
2. The parameters supported vary from vehicle to vehicle and are not related to OBD II, but rather to the vehicle's control unit.
